The world of Valcia is an unusual one at best. The world has a slight Earth-like curve to it as it the world was once spherical, however, it is that way no longer. The edges of the world will continue for some time until they eventually seem to taper off into nothing. Some believe that this world is connected to many other planes of existence as several reports of outsiders able to more easily enter this world without the use of powerful magic to force themselves in. As a result, some outsiders are able to maintain a longer stay as the universe seems to permit them longer here when they enter that way.
Additionally, people have reported that the borders can rapidly change, as buildings or constructions that were once safe disappear overnight into the void, the next day, it returns, though something always seems a bit different as it if aged rapidly though it was only gone for a day.
No one has ever returned after walking off the ‘edge of the world’.
